千家信白刚玉http://www.qjxnc.com/ 以工业氧化铝粉为原料，于电弧中经2000度以上高温熔炼后冷却制成，经粉碎整形，磁选去铁，筛分成多种粒度，其质地致密、硬度高，粒形成尖角状，适用于制造陶瓷、树脂固结磨具以及研磨、抛光、喷砂、精密铸造等，还可用于制造高级耐火材料。产品粒度按国际标准以及各国标准生产，可按用户要求粒度进行加工。通用粒度号为 F4~F220，其化学成份视粒度大小而不同。突出的特点是晶体尺寸小耐冲击，如果用自磨机 加工破碎，颗粒多为球状颗粒，表面干洁，易于结合剂结合。
White corundum with industrial aluminum oxide powder as raw material, in the electric arc melting temperature by more than 2000 degrees after cooling is made by crushing, plastic, magnetic separation to iron, sieve into a variety of size, its dense texture, high hardness, grain form sharp, suitable for the manufacture of ceramics, resin grinding tool grinding, polishing and consolidation, sandblasting, precision casting, also can be used in the manufacture of high-grade refractory materials. Particle size of products according to international standards and national standards of production, according to user requirements for processing granularity. Universal size is F4~F220, its chemical composition varies depending on grain size. The prominent feature is the small crystal size, impact resistance, if broken from the processing mill, particles as spherical particles, surface clean, easy to binder.
